Question

PROJECT: ENERGY FLOW IN ECOSYSTEMS Assignment Directions: Part 1: Draw and describe a food chain that shows the flow of energy between IMAGINARY organisms. Be sure to create at least seven make-believe organisms. Part 2: Then, draw an energy pyramid for at least three of the organisms from your food web. Show how energy varies as you move up the pyramid. Part 3: Label the tropic level for each organism (producer, primary consumer, secondary consumer, etc). Assignment Guidelines: Drawing correctly shows connections between organisms and demonstrates an understanding of food webs, trophic levels, and energy pyramids. Drawing is neat and interesting to look at. Drawing has correct spelling and labeling. Submission Requirements: A picture and description of a food chain and an energy pyramid When submitting written assignments, please remember to: Submit the assignment question(s) and your responses. Proofread for spelling, grammar, and punctuation.

Answer 1

Answer:

The food chain showing seven organisms can be drawn as follows:

Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers

The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.

An energy pyramid for three of the organisms can be shown as follows:

               mice (10 kilocalories)

                    ↑

         Grasshoppers (100 kilocalories)

                    ↑

        Plants ( 1000 kilocalories)

As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.
